The focus of this study was to explore and expand capabilities, sustainability and gender justice in Science, Mathematics and Technical subjects (SMTs) in teacher education curriculum practices as a process of Education for Sustainable Development in two case studies in Zimbabwe and South Africa. The study begins by discussing gender and science education discourse, locating it within Education for Sustainable Development discourse. Through this nexus, the study was able to explore gender and sustainability responsiveness of the curriculum practices of teacher educators in Science, Mathematics and Technical subjects; scrutinise underlying mechanisms that affect (promote or constrain) gender and sustainability responsive curriculum practices; and understand if and how teacher education curriculum practices consider the functionings and capabilities of females in relation to increased socio-ecological risk in a Southern African context. Influenced by a curriculum transformation commitment, an expansive learning phase was conducted to promote gender and sustainability responsive pedagogies in teacher education curriculum practices. As shown in the study, the expansive learning processes resulted in (re)conceptualising the curriculum practices (object), analysis of contradictions and developing new ways of doing work. Drawing from the sensitising concepts of dialectics, reflexivity and agency, the study worked with the three theoretical approaches of Cultural Historical Activity Theory (CHAT), feminist theory and capabilities theory. The capability and feminist lenses were used in the exploration of gender and sustainability responsiveness in science teacher education curriculum practices. CHAT, through its associated methodology of Developmental Work Research, offered the opportunity for researcher and participants in this study to come together to question and analyse curriculum practices and model new ways of doing work. Case study research was used in two case studies of teacher education curriculum practices in Science, Mathematics and Technical subjects, one in Zimbabwe and one in South Africa. Each case study is constituted with a networked activity system. The study used in-depth and focus group interviews and document analysis to explore gender and sustainability responsiveness in curriculum practices and to generate mirror data. Inductive and abductive modes of inference, and Critical Discourse Analysis were used to analyse data. This data was then used in Change Laboratory Workshops, where double stimulation and focus group discussions contributed to the expansive learning process. Findings from the exploration phase of the study revealed that most teacher educators in the two case studies had some basic levels of gender sensitivity, meaning that they had ability to perceive existing gender inequalities as it applies only to gender disaggregated data especially when it comes to enrolment and retention. However, there was no institutionalised pedagogic device in place in both case studies aimed at equipping future teachers with knowledge, skills, attitudes and values to promote aspects of capabilities (well-being achievement, wellbeing freedom, agency achievement and agency freedom) for girls in Science, Mathematics and Technical subjects. Science, Mathematics and Technical subjects teacher educators' curriculum practices were gender neutral, but in a gendered environment. This was a pedagogical tension that was visible in both case studies. On the other hand, socio-ecological issues, in cases where they were incorporated into the curriculum, were incorporated in a gender blind or gender neutral manner. Social ecological concerns such as climate change were treated as if they were not gendered both in their impact and in their mitigation and adaptation. It emerged that causal mechanisms shaping this situation were of a socio-political nature: there exist cultural differences between students and teacher educators; patriarchal ideology and hegemony; as well as other interfering binaries such as race and class. Other curriculum related constraints, though embedded in the socio-cultural-political nexus, include: rigid and content heavy curriculum, coupled with students who come into the system with inadequate content knowledge; and philosophy informing pedagogy namely scientism, with associated instrumentalist and functionalist tenets. All these led to contradictions between pedagogical practices with those expected by the Education for Sustainable Development framework. The study contributes in-depth insight into science teacher education curriculum development. By locating the study at the nexus of gender and Science, Mathematics and Technical subjects within the Education for Sustainable Development discourse, using the ontological lenses of feminist and capabilities, it was possible to interrogate aspects of quality and relevance of the science teacher education curriculum. The study also provides insight into participatory research and learning processes especially within the context of policy and curriculum development. It provides empirical evidence of mobilising reflexivity amongst both policy makers and policy implementers towards building human agency in policy translation for a curriculum transformation that is critical for responding to contemporary socio-ecological risks. / Microsoft� Word 2010 / Adobe Acrobat 9.54 Paper Capture Plug-in

Student performance in Mathematics and Science education is a source of concern for education authorities in South Africa. This was supported by the latest TIMSS results which were released in December 2004. As in the previous studies, TIMSS and TIMSS-R, South African learners were again outperformed by the learners of all other participating countries (Reddy, 2004). To ensure learner achievement in mathematics and science, we need committed, qualified and experienced teachers in these subjects. In this study a holistic professional development (HPD) model was constructed, tested and evaluated using practicing Grade 10 - 12 teachers. The model developed teachers' content knowledge, teaching approaches and professional attitudes simultaneously. After analysis of the model we found that improving teachers' content knowledge builds their confidence in teaching their subject. This in turn motivates teachers to perform better in their jobs: they come to class better prepared, eager to do a job they know they are good at, no more coming late, no more plodding through uninspiring one-way lessons. They are turned into better professionals with a positive work ethic. Their improved classroom practices lead to higher enrolments of science learners and improved learner achievement, the crown of successful science teaching. The HPD model was developed in three phases. In the first phase baseline information was obtained to determine problems that exist with the teachers' content knowledge, teaching approaches and professional attitudes. After data analysis it was found that all three of these dimensions needed development. In the second phase the initial development of the HPD model took place. An intervention programme was structured and the effect of the programme on the teachers' content knowledge, teaching approaches and professional attitudes were analysed. Successful elements of the initial model were extracted and developed further, in addition new elements were added. In the third phase the HPD model was developed further. Analysis of the data showed the following effect on the teachers: they were extricated from a vicious cycle where poor content knowledge leads to lack of confidence which caused unwillingness to spend time on task (poor professional attitudes, ineffective teaching approaches). Instead they became part of a virtuous circle where improved content knowledge leads to increased confidence, enjoyment and a willingness to spend more time on task (better professional attitudes and effective teaching approaches). The HPD model was evaluated using international benchmarks, such as the Standards for Professional Development of the National Research Council of New York, USA. Recommendations and possibilities for future research are discussed. / Mathematical Sciences / D.Phil.(Mathematics, Science and Technology Education - Physics Education)

Learners’ Physical Science performance in South Africa has been under discussion for several years, the challenge being that it has been exacerbated by continuous changes in the curriculum. Systems that have been put in place have yielded insufficient satisfactory solutions to both underperformance in the subject and sustainable good performance. Although interventions by curriculum policymakers have been ineffective, the issue at hand remains that teachers need to implement good teaching practices in order to ensure that all learners receive quality education. Physical Science teachers are custodians of a subject that may address scarce skills in the education system, so the quality of teaching must be optimised. Teachers need to implement intervention processes put in place by other stakeholders to reduce the negative perceptions that most people have about Physical Science. This study investigates how various factors related to the quality of teachers may affect the performance of Grade 12 learners in this subject. Since past studies have presented a broad spectrum of these factors, this study has categorised them as those directly related to teaching and those indirectly related to teaching. As a basis for data collection the researcher first established the overall status of the Physical Science teachers and investigated how the factors identified affect teaching. A mixed method approach was followed, and given the breadth of the study, available raw data was collected through questionnaires, interviews and observations. Data collected on factors indirectly related to teaching showed that these factors affect factors directly related to teaching and both of them affect the performance of the teacher, and consequently those of learners. These findings revealed that the performance of Physical Science cannot be based on one factor only, but on a combination of factors that are interrelated and should be integrated for effective teaching practices. Recommendations have been made to the National and Provincial Department of Education, District offices, school management teams and Physical Science teachers to reinforce other strategies that have been in place in order to improve or sustain good performance of the subject and to close gaps that have not been identified as possible intervention strategies. They include upgrading qualifications with the current content and methodologies to match the changing curriculum, restructuring workshops so that they are informed by the teacher’s needs, stabilising the curriculum to avoid many changes in short periods of time, retraining of teachers, relevant appointment of Heads of Departments (HoDs) into subject management positions, utilisation of support groups by teachers, proper management of the subject, proper screening of Physical Science learners and provision of teaching and learning resources. / Science and Technology Education / M.

The thesis aimed at explaining why some Zimbabwean teachers have migrated to South Africa while others have not despite experiencing the same economic and political crisis. The focus was on external secondary brain drain, which is the movement of human resources from one country to another within the Southern African Development Community region (SIRDIC, 2008). It was premised on the theoretical argument that uneven development in the SADC region sustains the movement of human resources from the poorer countries to the richer or ‘core’ countries in the region particularly South Africa. The thesis reviewed literature on the Zimbabwean crisis and conducted a quantitative field survey, which was supplemented by a qualitative aspect, in order to analyse the determinants of teacher migration to South Africa. The field survey involved the self-administration of questionnaires by 200 Zimbabwean teachers, half of them teaching in South Africa and the other half in Zimbabwe, as well as collected life stories from five migrant teachers, interviewed four school heads, and perused circulars. The research found that Zimbabwe’s reversed economic growth and social development constituted the background on which teacher migration occurred. This brain drain, which mainly involved highly qualified and specialised mathematics and science teachers, coincided with the peak of the Zimbabwean crisis around 2008 indicating its survival significance. Teacher migration continued after 2008 due networks and teachers’ salaries that remained inadequate as they were close to the poverty line. Several recommendations were made including strategies for reducing the brain drain. / Development Studies / D. Litt. et Phil. (Development studies)

Thesis (PhD)--Stellenbosch University, 2013. / Bibliography / ENGLISH ABSTRACT: This study investigated a single research question, that is: How do teachers experience the implementation of the Further Education and Training (FET) National Curriculum Statement (NCS) for Physical Science? The focus of the study was on searching the inner consciousness of Physical Science teachers as they engaged with the teaching of the subject on a daily basis. It is in the inner consciousness where one finds the truth about people’s perceptions, beliefs, emotions, challenges and convictions about/towards phenomena that the study sought to determine. In so doing, this study searched for phenomenological truth about the daily realities Physical Science teachers are faced with, as they implement the NCS. Phenomenological truth is floatable, precarious in nature, and subject to an individual’s perception of truth. It is important to note that phenomenological truth makes no reference to absolute truth. At the time this study was conducted the NCS was the only policy document with legal status for schools in South Africa. As a result the NCS influences and directs the pedagogical practices of teachers. This is because the NCS has a specific expectation of Physical Science teachers with regards to their understanding of the content, the delivery of the content, the learning environment, and professionalism. Through searching the consciousness of teachers, they revealed how they experienced what they do in the Physical Science classroom. In other words, how they experience what, how, when and who they teach. Probing into the consciousness of teachers and how they experience the implementation of the NCS provides valuable insight into the quality of curriculum delivery. This study did not only focus on the implementation of the NCS, but also examined why it might be difficult for teachers to change their practices. Phenomenology is both a theory and a method. The study was guided by the ideas of Edmund Husserl - who is regarded by many phenomenologists as the father of phenomenology, Martin Heidegger, Maurice Merleau-Ponty, and many other phenomenologists. Husserl (cited in Derrida, 1967) believed that we should begin any explanation with experience, which is a scientific description that does not presuppose any significance of the existence of the metaphysical world. By delving into the complexities of experience one can locate the flowing life of an individual’s consciousness as it occurs. Husserl posited the belief returning to the things themselves (cited in, Derrida, 1967; Spanos, 1976; Groenewald, 2004) to describe the purity of experience as data. In this study I sampled three teachers and employed a phenomenological methodological framework to capture their lived experiences. I used one-on-one semi-structured face-to-face interviews to construct the data. In addition, field notes were used to turn the direct experiences and observations of the participants into vivid descriptions. In phenomenology researchers use field notes to make the voice of people heard in the text. I drew on Husserl, Heidegger and Merleau-Ponty’s philosophical pathways that a person must be understood from his position within a specific time and place to present the findings. The major finding in this study showed that the teachers’ consciousness, with respect to Physical Science teaching was negatively influenced by the legacy of apartheid-education. This negative consciousness through which they framed their thoughts and filtered their ideas became the collective mindset through which they personified their teaching. The study revealed that the delivery of the NCS (by the teachers) was mostly axiomatised by old habits and images in their thoughts engrained in their memory under apartheid education. The findings also showed that their (teachers’) consciousness with regards to the NCS unconsciously oscillated between the present and the past and that they continuously and unconsciously bring the past (old ideas and beliefs) into the present. The teachers constantly have to struggle against the phenomenological self or attitude and ceaselessly suppose and follow thoughts of pre-comprehension or preconception. / AFRIKAANSE OPSOMMING: Die doelwit van hierdie studie was om die volgende navorsingvraag te beantwoord: Hoe ervaar onderwysers die implementering van die Verdere Onderwys en Opleiding (VOO) Nasionale Kurrikulum Verklaring (NKV) vir Fisiese Wetenskap? Die hoofdoel was om meer insig te verkry oor wat binne onderwysers se psige plaasvind soos hulle op ‘n daaglikse basis hul uitleef in die Fisiese Wetenskapsklaskamer binne die raamwerk van die NKV. Dit is binne die psige waar hul persepsies, diepgewortelde waardes, emosies, en uitdagings rondom die NKV rus. Om hierdie rede is die studie geïntresseerd om die fenomenologiese waarheid van die alledaagse realiteite waarmee hulle aanhoudend gekonfronteer word, te myn. Fenominologiese waarheid is vloeibaar en verskil van persoon tot persoon en hou geen verwysing met absolute waarheid nie. Toe hierdie studie plaasgevind het, was die VOO NKV die enigste wettige beleidsdokument vir die deelnemers. Die onderwysers was dus verplig om die voorgeskrewe beginsels soos in die NKV saamgevat toe te pas in die voorbereiding en aanbieding van hul lesse. Die NKV beskryf in diepte die inhoud vir elke graad (10-12), hoe die inhoud aangebied moet word, die klaskamer atmosfeer, asook die professionalitiet van die opvoeders. Al die antwoorde soos saamgevat in laasgenoemde, lê bine die psige van die onderwysers. Die ondersoek van die psige van die onderwysers lei tot ‘n begrip van hoe, wat en waarom Fisiese Wetenskaps-onderswysers doen wat hulle doen. Alhoewel die fokus van hierdie studie op die implementering van die NKV is, dra dit ook by tot groeiende kennis aangaande hoekom onderwysers dit moeilik vind om hulle praktyke te verander wanneer dit kom by die hernuwing van ‘n kurrikulum. Fenomenologie is beide ‘n navorsingsmetode en ‘n teorie. Die literatuuroorsig van hierdie studie is geinspireer deur die idees van Edmund Husserl, wat bestempel word as die vader van fenomenolgie, asook Martin Heidegger, Maurice Merleau-Ponty, en veskeie ander fenomenoloë. Derrida (1967) is oortuig daarvan dat enige verduideliking akkuraat beskryf kan word indien geleefde ervaring in ag geneem word. Geleefde ervaring spreek direk tot die onderliggende psige van ‘n individu, en deur die psige te ondersoek, is dit moontlik om ‘n individu se oortuigings ten opsigte van sy/haar geloof, persepsies en uitdagings, asook hoe die individu reageer op hierdie aspekte te verstaan. Husserl gebruik die uitdrukking ‘returning to the things themselves’ wanneer hy verwys na die belangrikheid en oorspronlikheid van ervaring (vermeld in, Derrida, 1967; Spanos, 1976; Groenewald, 2004). Om hierdie rede is ‘n fenomenologiese metode gevolg om die lewenservaringe van drie swart onderwysers vas te vang. Hierdie fenomenologiese vertolkende ondersoek word deur veelvoudigemetodes van inligtingsinsameling gekenmerk. Inligting in hierdie studie oor die deelnemers se ervaringe is vekry deur middel van individuele onderhoude, en die ontleding van die inhoud daarvan. Addisionele inligting is verkry deur veldnotas. Die doelwit van die veldnotas was om die deelnemers se direkte ervaringe en waarnemings in besonderhede te beskryf. Die ontledingsbenadering van elke deelnemer is gedoen binne die raamwerk van Husserl, Heidegger en Merleau-Ponty wat gegrond is op teorieë wat die belangrikheid van plek en tyd uitbeeld. Die resultate van hierdie studie het getoon dat die onderliggende psige van elke deelnemer deur die nalatenskap van apartheid negatief beïnvloed is. Hierdie negatiewe denkpatrone waardeur die onderwysers se idees formuleer vorm die kollektiewe ingesteldheid waardeur hulle hul onderrigswêreld skep. Verder het die studie onthul dat hul aanbieding van die NKV meestal gedryf word deur ou gewoontes wat binne hul denke gekristalliseer het. Hulle vind dit dus moeilik om deur hierdie ou gewoontes te breek. Hul denke wissel gedurig tussen die verlede en die hede en roep die verlede voortdurend binne die hede. Alhoewel die bevindinge van hierdie studie gekoppel is aan plek en tyd is daar ‘n konstante struweling tussen die fenomenologiese self en hul ou gesette denke.

The Next Generation Science Standards represent a significant challenge for K-12 school reform in the United States in the science, technology, engineering and mathematics (STEM) disciplines (NSTA, 2012). One important difference between the National Science Education Standards (NRC, 1996) and the Next Generation Science Standards (Achieve, 2013) is the more extensive inclusion of nanoscale science and technology. Teacher PD is a key vehicle for implementing this STEM education reform effort (NRC, 2012; Smith, 2001). The context of this dissertation study is Project Nanoscience and Nanotechnology Outreach (NANO), a secondary level professional development program for teachers that provides a summer workshop, academic year coaching and the opportunity for teacher participants to borrow a table-top Phenom scanning electron microscope and a research grade optical microscope for use in their classrooms. This design-based descriptive case study examined the thinking of secondary teachers in the 2012 Project NANO cohort as they negotiated the inclusion of novel science concepts and technology into secondary science curriculum. Teachers in the Project NANO 2012 summer workshop developed a two-week, inquiry-based unit of instruction drawing upon one or more of nine big ideas in nanoscale science and technology as defined by Stevens, Sutherland, and Krajcik (2011). This research examined teacher participants' metastrategic thinking (Zohar, 2006) which they used to inform their pedagogical content knowledge (Shulman, 1987) by focusing on the content knowledge teachers chose to frame their lessons, their rationales for such choices as well as the teaching strategies that they chose to employ in their Project NANO unit of instruction. The study documents teachers various entry points on a learning progression as teachers negotiated the inclusion of nanoscale science and technology into the curriculum for the first time. Implications and recommendations for teacher professional development are offered.

Esta pesquisa se desenvolve no âmbito do ensino de ciências, no que tange à formação continuada de professores de Ciências e sequências didáticas. Objetivando-se obter um levantamento palpável sobre as concepções dos professores de Ciências sobre Ciência e Tecnologia (C&T), foram utilizadas duas ferramentas de coletas de dados: Uma enquete e sequências didáticas (SD) desenvolvidas pelos professores cursistas participantes do Curso de Especialização em Ensino de Ciências da Faculdade de Educação da USP no Programa Rede de Formação Docente (EEC-FEUSP-REDEFOR) durante o segundo ano de oferecimento, 2011-2012. O foco principal do presente estudo é sistematizar as concepções sobre C&T dos professores cursistas e observar como estas permeiam o desenvolvimento de SD, para que se obtenham subsídios e reflexões sobre os objetivos da educação científica, da formação de professores e do entendimento dos professores de ciências sobre as questões sócio científicas (QSC). A análise dos dados se desenvolveu utilizando duas abordagens, quantitativa e qualitativa, de forma a se complementarem. As análises estatísticas nomeadas análise multifatorial e de cluster, e abordagem qualitativa descritiva documental dos resultados sustentam a análise como um todo, interpretando os resultados obtidos, trazendo assim uma visão ampla do objeto de estudo que aponta a presença de dez tipos de concepções, 8 tipos de perfis de concepções sobre C&T que se traduzem nas SD em categorias sintéticas como: conhecimento científico prediz, reverte e evita problemas ambientais; conhecimento científico explica e viabiliza melhoria de vida; C&T beneficiam sociedade e ambiente; homem prejudica e desperdiça; preocupação simplória com a degradação ambiental; conteudismo; aproximação CTS e consciência de bem social global; funcionalidade e acesso ao conhecimento científico; conhecimento científico e visões alternativas, e finalmente, impactos do desenvolvimento científico e tecnológico no meio ambiente. A importância de se reconhecer tais variações e sentidos das concepções mais comumente expressas se revela à medida que configuram tópicos de discussão relevantes aos cursos de formação inicial e continuada de professores e a observação da forma como estas SD poderiam sintetizar concepções mais ricas de possibilidades de discussões em sala de aula. / This research develops in the scope of science teaching, in what concerns to in service formation science teachers and didactic sequences. In order to obtain a palpable survey on the conceptions of the teachers on Science and Technology (S & T), two data collection tools were used: a survey and didactic sequences (DS) developed by the teachers participating in the Specialization Course in Science Teaching of the Faculty of Education of USP in the Program of Teacher Education (EEC-FEUSP-REDEFOR), along the second year (2011-2012). The main focus of the present study is to systematize the conceptions about Science and Technology of the teachers and to observe how they permeate the development of DS, to obtain subsidies and reflections on the objectives of scientific education, teacher training and teachers\' understanding Sciences on socio-scientific issues (SSI). The analysis of the data was developed using two approaches: quantitative and qualitative, in order to complement each other. The statistical analyses named multifactorial and cluster analysis, and qualitative documentary descriptive approach of the results support the analysis as a whole, interpreting the results obtained, thus bringing a broad view of the object of study that points out the presence of ten types of conceptions, 8 types of profiles of S & T conceptions that translate into DS in synthetic categories such as: Scientific knowledge predicts, reverses and avoids environmental problems; Scientific knowledge explains and enables improvement in life; Society and Environment; Man harms and wastes; Simplistic concern with environmental degradation; Content; CTS approach and global social welfare awareness; Functionality and access to scientific knowledge; Scientific knowledge and alternative visions, and finally, Impacts of scientific and technological development on the environment. The importance of recognizing such variations and meanings of the most commonly expressed conceptions is revealed by the fact that they configure topics of discussion relevant to the initial and in service formation courses and the observation of how these DS could synthesize richer conceptions of possibilities for discussion In the classroom.

Resumo Sob o enfoque do trabalho colaborativo esta pesquisa qualitativa pretende contribuir, com seus resultados, para ampliar informações com relação ao desenvolvimento profissional do formador de professores de ciências. O interesse está em viabilizar caminhos que promovam a melhoria tanto na formação dos professores, como no próprio ensino de ciências nas séries iniciais, através da formação dos formadores de professores de ciências. Compreendemos que pouco adianta os investimentos em formação de professores se não voltarmos nossas atenções para aquele profissional que é responsável por essa formação, por exemplo, o Assistente Técnico Pedagógico, que atua nas Diretorias Regionais de Ensino. Através de uma proposta de ensino de ciências para as séries iniciais, por meio de atividades investigativas no contexto da física, surge a iniciativa de nove Assistentes Técnico Pedagógicas (ATP), formadoras de professores de ciências, em realizar um projeto de melhoria no ensino, integrando a universidade, as diretorias regionais de ensino e as escolas públicas. O projeto O conhecimento físico no ensino fundamental: dos programas de formação continuada à implementação de novas práticas em sala de aula, financiado pela FAPESP, é o objeto de estudo da presente pesquisa, que contou com dados coletados em diferentes instâncias ao longo do período em que a pesquisadora acompanhou o Grupo das ATP. Dentre os dados analisados, destacam-se fragmentos de reuniões realizadas na universidade e nas diretorias de ensino, entrevistas, relatórios e outras produções escritas do grupo. A investigação possibilitou uma compreensão mais ampla sobre a formação de formadores de professores e, neste sentido, merece destaque a construção de um ambiente efetivamente colaborativo entre os participantes do processo, que pode ser relacionado, entre outros, a uma constante valorização dos saberes trazidos por cada uma das ATP. / Abstract Under the focus of cooperative work, this qualitative research intends to contribute, with its results, to enlarge information with regard to the professional development of the teachers of sciences teachers. The interest is in make possible ways that promote the improvement of teachers of teachers, and of the science education in primary school, through the formation of the teachers of science teachers. We understand that the investments on teachers\' formation are not successful if we do not pay attention for that professional who is responsible for this formation, for example, the Assisting Pedagogical Teaching, which acts in the Regional Directories of Teaching. Through a science teaching proposal for the primary school, by means of investigative activities in the context of physics, arises an initiative of nine Assisting Pedagogical Technician (ATP), teachers of sciences teachers, in accomplish an improvement project in the teaching, integrating the university, the regional directories of teaching and the public schools. The project The physical knowledge in the fundamental teaching: of the formation programs continued to the new practices implementation in class room, financed by the FAPESP, is the study object of this research, which relied on data collected in different instances along the period in which the researcher accompanied the Group of ATP. Among the analyzed data, we highlight meetings fragments accomplished at university and in the teaching directories, interviews, reports and another writings productions of the group. The investigation enabled a wider comprehension about teachers formation and, in this sense, deserves highlight the construction of an indeed cooperative environment among participants of the process, which can be related, among others, to a constant valorization of the knowledge brought by each one of ATP.

An exploratory case study research design was followed to explore and categorize 23 pre-service physics teachers’ understanding in the fields of superconductivity and nanotechnology at the Sultan Qaboos University in Oman. To elicit their responses, a five-stage categorical framework analysis was used. The five stages included identification of the thematic framework, familiarization, coding, placing the categories on a chart and finally, interpretation. A conceptual survey test (Conceptual Survey of Superconductivity and Nanotechnology) was administered to the pre-service physics teachers to form four independently homogenous ability focus groups. This was followed by focus group discussions whose data were analyzed to group their conceptions in both the epistemological as well as ontological categories. From the focus group discussions, six categories were considered from previous studies, namely; lateral alternative conceptions, ontological conceptions, naïve physics, Ohm’s p-primes, mixed conceptions and loose ideas. Since this was a pre-instructional study, naïve physics ideas and lateral alternative conceptions were dominant. Naïve physics refers to the untrained student or human perception of various physical phenomena while lateral alternative conception refers the misconceptions individuals have on ideas that may be inconsistent with scientifically acceptable facts. Findings indicate that the pre-service teachers’ conceptions deviated from canonical scientific concepts, are diversified and inconsistent. The knowledge on pre-instructional conceptions will influence the development of evidence-based pedagogy, which is fundamental to the development of an effective physics education curriculum. / Institute for Science and Technology Education (ISTE) / M.

The Framework for K-12 Science Education, the foundation for the Next Generation Science Standards, identifies scientific explanation as one of the eight practices "essential for learning science." In order to design professional development to help teachers implement these new standards, we need to assess students' current skill level in explanation construction, characterize current teacher practice surrounding it, and identify best practices for supporting students in explanation construction. This multiple-case study investigated teacher practice in eight high school science inquiry units in the Portland metro area and the scientific explanations the students produced in their work samples. Teacher Instructional Portfolios (TIPs) were analyzed with a TIP rubric based on best practices in teaching science inquiry and a qualitative coding scheme. Written scientific explanations were analyzed with an explanation rubric and qualitative codes. Relationships between instructional practices and explanation quality were examined. The study found that students struggle to produce high quality explanations. They have the most difficulty including adequate reasoning with science content. Also, teachers need to be familiar with the components of explanation and use a variety of pedagogical techniques to support students' explanation construction. Finally, the topic of the science inquiry activity should be strongly connected to the content in the unit, and students need a firm grasp of the scientific theory or model on which their research questions are based to adequately explain their inquiry results.
